The natural phenomenon that makes it appear that lava is flowing over a cliff at Yosemite National Park is back, but only for a few days.

“Firefall” is the name for the natural magic trick that creates the illusion at the park in California. It comes to life when the setting sun causes light to hit the waterfall at just the right angle.
